finally got my main jet right a brownish collar thinking maybe the pilot screw is off at mid to a little less throttle to full runs perfect but barely open before powerband kicks in riding slow kindoff pops and cracks a lot and jumps a little has quick throttle response revs perfect could it be the pilot screw a little off:-/
jetting issue
- Thread starter will9084
- Start date
pilot jet should be set and determined with the airscrew, and should be done first as it effects the othee 2 ranges
turn it a 1/4 turn at a time starting at 1 1/2 turns out, try both directions and let the motor catch up for about 20 seconds after each 1/4 turn, the aircscrew setting is correct when the motor idles the highest, then under 1 turn out needs a bigger pilot, and over 2 - 2 1/2 turns out could use a smaller pilot
then turn it an 1/8 turn at a time till it will rev cleanly and rip sh*t up !!!!!
then recheck the other circuts, needle and main as like i said, the pilot is always pulling fuel, and will richen or lean the needle and main settings

after that if it runs fine mid and full they would be fine wouldnt they so from 1 to 2 the jet i have would be fine right
